I have been diagnosing this problem for a while now and need to get a few more questions answered. I replaced the ball and hooked up the test fixture and here are the results.
The pump settles out at 640 psig
Turns on at 480 psig
The switch closes at 350 psig
The accumulator pre-charge is right at 300 psig
All this seems to check out ok but the pedal can be pushed all the way down with enough foot pressure. I don't believe it should be this way. Please confirm?
The other thing is that the pump turns on every other time I push on the pedal. Is this normal?
There are no leaks in the system and I bled the brakes so there is no air in the system.
I'm thinking that the master cylinder could be bad and therefore leaking by the seals causing the pedal to go down so far. I am not aware of any method to check the MC for this. Is there any? What are your thoughts of this? Thanks kindly.

PS I am not interested in changing the brake system as I am set on getting this to work. Thanks
